Researchers from Hebrew University of Jerusalem have developed Random Antimicrobial Peptide Mixtures (RPMs) as an alternative to antibiotics in cultured meat production. The study, published in Food Chemistry: Molecular Sciences, shows RPMs effectively combat bacterial contamination without harming host cells or slowing differentiation. They demonstrated strong activity against both Gram-positive and Gram-negative bacteria. RPMs break down quickly during digestion, posing no bioaccumulation risk. This innovation could enhance safety, regulatory compliance, and sustainability in cellular agriculture. The team is now exploring industrial applications and regulatory pathways for RPMs.
